This function is used to create Rib on the boundary edge of flange. The Rib dialog box is illustrated in Figure 6.5.27.

RIB LIST
All the created ribs are added to this list illustrated in Figure 6.5.27. The selected rib is highlighted in the graphic display area.
ADD
Click Add to prompt the user to specify a point on the boundary edge of flange as the base point for rib.
DEFINE BASE POINT ON BOUNDARY EDGE
After the base point is defined, the program will generate rib frame at the base point, as illustrated in Figure 6.5.28.
Figure 6.5.28 Rib frame
Note: If the base point is not on boundary edge, the program will prompt the user that Rib cannot be created at this point.
DELETE
Select the rib to be deleted in the rib list. Click this button to delete the selected rib.
RIB PARAMETERS
The program will create a rib by defining 5 parameters illustrated in Figure 6.5.29.
Figure 6.5.29 Rib parameters
These 5 parameters are: rib length (L), radius 1 (R1), radius 2 (R2), radius 3 (R3) and radius 4 (R4).
Elongate
After the Rib frame is generated, the program will automatically calculate elongate of rib:
Elongate=(Arc1+Arc2+Arc2)/W
Figure 6.5.30 Elongate
Preview
Click Preview after the rib parameters are modified by the user. The program will regenerate rib frame according to the new parameters.
Swap
Clicking this button, the program will generate Rib frame on the other side of flange.
Move
The user can click Move button to redefine the base point of rib. After the new base point is selected, the program will regenerate rib frame according to the defined rib parameters.
Apply
Click Apply button to create Rib. The generated Rib is illustrated in Figure 6.5.31.
